These louvers are gravity operated. The blades open when your roof-mounted exhaust fan goes on and close when it'soff, preventing backdrafts. The felt seal on the face of the blades ensures quiet closing and better protection from the weather.

Mountingbases are sold separately. Louvers fit the bottom of the mounting base and must be secured to the lip of the base with sheet metal screws(notincluded).

Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. These exhaust fans draw stagnant and humid air out through your roof and then expel it up and away from the roof surface. All fans have a disconnect switch to turn off the power for servicing.

Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

Fans are AMCA (Air Movement and Control Association)rated.
